Here is v4.

0001 - addresses the comments made by Bertrand.
0002 - makes JumbleState a constant when passed to post_parse_analyze
and updates all downstream code that consume the JumbleState. This
means we now need to copy the locations from JState into a local/temporary
array when generating the normalized string.
